D
Men and women who serve in the United States armed forces are proud of the names like
doughboy and GI Joe．The names have e from the American Civil War．
After the American Civil War in the eighteen sixties，a writer in a publication called Beadle’s Monthly used the word doughboy to describe Civil War soldiers．But word expert Charles Funk says that early writer could not explain where the name started．
About twenty years later，someone did explain．She was the wife of the famous American general George Custer．Elizabeth Custer wrote that a doughboy was a sweet food served to Navy men on ships．She also said the name was given to the large buttons on the clothes of soldiers．For example，the soldiers enjoyed their new GI very much．They looked smart and felt fortable．Elizabeth Custer believed the name changed over time to mean the soldiers themselves．
By World War Two，soldiers were called other names．The one most often heard was GI, or GI Joe．Most people say the letters GI were a short way to say general issue or government issue．The name came to mean several things．It could mean the soldier himself．It could mean things given to soldiers when they joined the military such as weapons，equipment or clothes．And，for some reason，it could mean to organize，or clean．Soldiers often say，“We GI’d the place．”And when an area looks good．soldiers may say the area is“GI．”Strangely，though，GI can also mean poor work，a job badly done．
Some students of military words have another explanation of GI．They say that instead of government issue or general issue，GI came from the words galvanized iron．The American soldier was said to be like galvanized iron，a material produced for special strength．The Dictionary of Soldier Talk says GI was used for the words galvanized iron in a publication about the vehicles of the early twentieth century．
Today，a doughboy or GI may be called a grunt(咕哝声)．Nobody is sure of the exact beginning of the word．But，the best idea probably is that the name es from the sound that troops make when ordered to march long distances carrying heavy equipment．
